Answer:

0%

Explanation:

This is a typical monohybrid cross involving a single gene B.

Both parents are purebreeding or homozygous i.e. have identical alleles for the specified trait. Hence, in a cross between the two, all the offsprings will be heterozygous (Bb) i.e. possess different alleles for the trait (See attached image).

N.B: A genotype is the genetical make up of an organism.

Since the genotypes of all the possible offsprings will be Bb, there is none that will possess the same genotype as any of the parent. Hence, the percentage is 0% i.e. 0/4 × 100
